#### Answer

$P = 1.02\times 10^{-16}~atm$

#### Work Step by Step

We can find the pressure as: $PV = NkT$ $P = (\frac{N}{V})~(kT)$ $P = (\frac{100}{1~cm^3})(\frac{10^6~cm^3}{1~m^3})(1.38\times 10^{-23}~J/K)(7500~K)$ $P = 1.035\times 10^{-11}~Pa$ We then convert the pressure to units of atm: $P = (1.035\times 10^{-11}~Pa)(\frac{1~atm}{1.013\times 10^5~Pa})$ $P = 1.02\times 10^{-16}~atm$
